The SY8089AAAC is a 6-pin synchronous buck converter IC with the following pin functions:
1. VIN (Pin 1) – Input voltage supply (2.5V–5.5V).
2. SW (Pin 2) – Switching node connected to the inductor.
3. GND (Pin 3) – Ground reference.
4. FB (Pin 4) – Feedback input for output voltage regulation.
5. EN (Pin 5) – Enable control (high = active, low = shutdown).
6. PG (Pin 6) – Power-good indicator (open-drain output).
It provides up to 3A output current with high efficiency and integrates power MOSFETs. The PG pin signals when the output is within regulation.
